Why Flat-Fee Advice Matters for Foreign Service HouseholdsOne transparent fee that does not change just because your TSP went up.

For many Foreign Service households, the biggest financial decisions are not about which fund to buy. They are about retirement timing, pension elections, TSP withdrawals, taxes, allowances, housing, benefits, and cash flow across assignments. That is why an advisor’s fee structure matters. The way advice is priced should reflect the work being done.

Financial advisors charge in several ways. One common model is assets under management, or AUM, where the client pays a percentage of the assets the advisor manages. Another is flat-fee pricing, where the client pays an agreed-upon dollar amount for advice and service.

Both models can support a strong ongoing relationship and either can be appropriate depending on the client’s needs. For our firm, flat-fee pricing became the better fit because much of the value we provide to Foreign Service households comes from planning decisions that are not tied directly to the size of an investment account.

How AUM Pricing Works

The average AUM fee is often around one percent. That can sound small, which is part of the model’s appeal. But as a portfolio grows, the dollar cost rises too.

Under an AUM model, the advisor is paid more as managed account balances increase. The fee is tied primarily to assets under management, not necessarily to the complexity of the client’s broader financial life. That does not make the model wrong, but we ultimately concluded it was not the best fit for how we wanted to serve Foreign Service households.

We started our firm using the traditional assets-under-management model. At the time, it seemed like the right way forward. Over time, though, I became less comfortable with a fee structure where what a client paid was not always connected to the complexity of their situation or the value of the advice they received.

That created tension in the way I wanted to serve clients. Many Foreign Service clients hold a large share of their wealth in the TSP. I did not want to charge a percentage fee simply because a TSP balance was large, while still providing ongoing advice on the many planning decisions that happen outside the portfolio.

How Flat-Fee Advising Works Differently

A flat-fee advisor charges a fixed amount agreed upon in advance. The fee is based on the complexity of the client’s situation and the scope of the engagement, rather than the assets being managed. It does not change simply because a TSP balance grows, markets rise, or a rollover occurs.

That distinction matters because not every valuable planning question is an investment management question. Pension elections, PCS-related cash flow, OGE disclosures, tax planning, retirement timing, and withdrawal strategy all deserve serious attention, even when they do not increase assets under management.

For Foreign Service families, many of the most important decisions sit outside a managed portfolio. Variable income, overseas differentials, housing benefits, tax elections, survivor benefits, and the interaction between the FSPS pension and future cash flow can all shape long-term outcomes. AUM advisors can and do help with these issues. For our firm, though, percentage-based fees did not line up as well with the work we were actually doing for clients.

Why We Chose to Become a Flat-Fee Advisor

The decision was ultimately about alignment. By charging a flat, fixed fee, clients know what the invoice will say before it arrives: the dollar amount we agreed on in advance. With a percentage-based fee, the invoice changes as account balances change, even when the planning relationship has not materially changed.

Foreign Service planning also changes from assignment to assignment. Income, differentials, allowances, housing benefits, overseas expenses, taxes, and retirement timing can all shift over time. Those transitions create planning opportunities, but they also add complexity that often has little to do with the size of an investment account.

The same is true in retirement. For many Foreign Service households, the pension is a central part of their retirement income plan. The planning value often comes from understanding how that pension interacts with TSP withdrawals, Social Security, survivor benefits, healthcare costs, taxes, and retirement timing.

Ultimately, we concluded that it was more transparent to price our work around the service we provide than around an account balance that changes on its own.

That is the point of flat-fee planning for Foreign Service households. The advice is priced around the decisions that shape a household’s financial life: retirement timing, benefits, taxes, pensions, cash flow, and long-term planning, not just the size of the accounts available to manage.
